5 cze 2020 · Subsequent neuroanatomical and neurochemical studies revealed that most sensory fibres from the intracranial and the extracranial tissues originate in the fifth cranial nerve (CN V) ganglion, also called trigeminal ganglion (TG).
1 mar 2024 · TNO can present from the involvement of the fifth cranial nerve (CN V) anywhere in its course, from the nuclei in the brain stem to its peripheral branches. It can be caused by known etiologies such as traumas, tumors, rheumatologic diseases, demyelinating, or idiopathic ones.
The motor division of the trigeminal nerve innervates the “muscles of mastication,” while the best known disorder of the trigeminal sensory division is “trigeminal neuralgia.”. Facial expression is innervated by the facial nerve (VII) and is often abnormal in neuropsychiatric conditions.
Trigeminal neuralgia is characterized by sudden, brief, and excruciating facial pain attacks in one or more of the V branches, leading to a severe reduction in the quality of life of affected patients. Trigeminal neuralgia etiology can be classified into idiopathic, classic, and secondary.

3 mar 2024 · The trigeminal nerve has peripheral sensory components converging at the trigeminal ganglia that relay touch, pain, and temperature information from the ipsilateral face to the contralateral thalamus via the trigeminothalamic tract. The trigeminal nerve has 3 divisions: ophthalmic (V1), maxillary (V2), and mandibular (V3).
1 sie 2016 · Article. Figures & Data. Supplemental. References. Info & Metrics. PDF. Abstract. SUMMARY: Neurovascular compression syndromes are usually caused by arteries that directly contact the cisternal portion of a cranial nerve. Not all cases of neurovascular contact are clinically symptomatic.
